Yet Another Measles Warning Issued For Sydney's West

NSW Health have been forced to issue yet another measles warning for the city's west as a 29th person is diagnosed with the virus.

The patient has been confirmed to have visited two sites in Canterbury last Tuesday before he realised that he was contagious.

As a result, anyone who attended Canterbury Hospital on October 10 between 9.30am and 1pm and ALDI Canterbury between 1pm and 2pm is urged to be aware of developing measles themselves.

The virus is highly contagious and can be spread through the air by coughing or sneezing.

"Our public health units are contacting people known to have been in contact with this latest case to offer preventive injections where appropriate," director of communicable diseases Dr Vicky Sheppeard said.

"However it will not be possible to identify and contact all people who may have been exposed.

"We encourage people who were in the same locations as the latest case to keep a close watch for symptoms and get vaccinated."

Symptoms include fever, sore eyes and a cough followed by a red blotchy rash three or four days later.
